3D Touch Sensor:Auto-levelling for Geeetech 3D printer

[Mauri58]

Hi william , I've a I3 Pro B and I've installed the 3dtouch probe. I followed all the instruction for installation, wiring and firmaware changes. When I turned on first time the probe it has done the self test succesfully remaining in solid red. I've changed the script in Simplify3D putting G29 after the G28 for homing- The printer goes to 0 X and 0 Y and after goes in the middle of the bed. It starts to go down, when the probe touches the bed is becoming solid red but not stopping, if I don't push the emergency button is colliding with the bed. I tried to send commands trough the PC interface of Simplify3D but the probe is not reacting........

Any suggestion? Thanks a lot

Hi Mauri58
I think you should check the wires of the Z min.
Maybe you can try to：
Insert the wire after inverting 180°

Hello William, thanks for the prompt answer. I've checked all the wiring from the probe to the end connectors and I didn't find any interruption. I tried again plugging all the wires but nothing. I tried even how you suggested, inverting the Zmin connector, but nothing. The printer starts the homing, goes to the middle of the bed but the probe is solid red and retracted so not ready to measure the bed level even if it is going down, so I stop everything to avoid damages.

thanks
Maurizio

I think you can try to use these code check it work or not
1.M280 P0 S10
M280 P0 S90
M280 P0 S120
2.If it still won't work,you should check the fw of yours correct or not

Hello William, thanks again,
I followed your suggestion but nothing. When I send the G-Code instructions using Simplify3D interface I don't obtain any reaction. The probe is up and solid red, if I manually extract it the red light is turning off but nothing else. I've checked again the firmware but I don't find differences between the suggested one and my one. I don't have the G2560 A+ board, I have the older one and so I addressed: #define SERVO0_PIN 32//13 // untested, and not the PIN 11 like requested for the A+ board. I don't have the dedicated 3 pins connector.
I would like to send you the configuration.h file but I don't know how to attach it to the post.
It's frustrating, I can go back to the manual bed leveling but.....

Regards
Maurizio

Hello everyone, I have a problem with a geeetech i3 with a 3D touch sensor and a GT2560 A + board; I wired everything by following the manuals and tried to install the firmware for A+on page 1 but the sensor still does not work; at startup it correctly checks but then does not extend the arm to make the home; I also tried with the latest versions of marlin but without success; the sensor works correctly connected to an anet a8; can you help me?

I send you the loaded Marlin firmware.

You can upload this fw for it then test it

Hello William, thank you again.
I downloaded the fw and uploaded but nothing. I've checked the board mentioned, my one is considered ULTIMAKER, changed but nothing. Checked the pins, corrected, but nothing. Even the printer was not moving as before.
So I've given up for now, moved out the probe, still inside the cable tracker, wired back the Z min switch and reloaded the original fw with just the correction for T8. Now I can print again. I modelled and printed 4 little bracket to keep in position some M3 nuts instead the wing nuts under the bed so now i can do the manual leveling easily.
Thanks for your support

I think you should feedback it to the sales.
It seems the touch sensor broken.(Maybe you can use the Z max port for the signal pin then try it again)
